The wings are arranged at right angles to each other in a U-shape, being divided into a main wing and two side wings. The new building is used as a house for tropical plants, crops, and desert plants. The orangery connects the existing subtropical house with the exhibition greenhouse over a length of about 100 m (328 ft).
The German Dlubal customer ASSMANN BERATEN + PLANEN AG was responsible for the structural analysis of the steel structure. The structural frame and truss analysis software RSTAB was used for the structural design.
Structure
The exhibition greenhouse is a steel structure with a glass roof. The external dimensions of the main area (tropical house) are L x W = 55 m x 21 m (180 ft x 69 ft); those of the two smaller areas (desert house and crop house) are each L x W = 34 m x 12 m (112 ft x 39 ft).
The principal beams of the greenhouse are slender, curved IPEo sections, which are arranged in a spacing of 3 m (10 ft). The height of the large arches is about 17 m (56 ft) and that of the small arches is about 8 m (26 ft).
Due to the shape of the arches, the stiffening in the transverse direction is achieved by a two-hinged frame. In the longitudinal direction, the arches are connected by regularly distributed coupling members. These members transfer the stiffening loads into the roof and wall bracings and thus into the foundation.
